摘要

在现代条件下,随着信息和通信技术(包括虚拟现实和数字孪生)的广泛应用,在工业 4.0 和无损检测 4.0 范式的关键领域,使用数字工业技术最大限度地实现各种生产流程的自动化和创建无人技术是生产技术发展的主要方向。为实现数字化无损检测,提出了面向服务的方法,作为获取、处理和存储各类检测结果数据的有效解决方案,并给出了该解决方案的基本架构。考虑了工业射线照相实验室的模拟器模型,在获取图像时构建了对象数字双胞胎的离散模型,为此使用了集合论的基本规定和工具。举例说明了数字孪生体数学模型与其图形对应物的对应关系,以及在探测器上形成的图像是建模和执行辐射类无损检测的结果。需要指出的是,对工业射线照相实验室这样复杂的技术设施进行虚拟化,可以在短时间内以最低成本验证技术解决方案和工程假设的可行性,同时考虑到实际生产条件和需求,一方面提供技术操作实施的可变性,另一方面根据无损检测的辐射类型增加训练有素的合格专家的数量。

THE USE OF DIGITAL TWINS MODELS WHILE A RADIOGRAPHIC IMAGE FORMATION IN A VIRTUAL REALITY ENVIRONMENT
In modern conditions, the use of digital industrial technologies for maximum automation of various production processes and the creation of unmanned technologies is the main direction of technological development of production in the key of the Industry 4.0 and NDE 4.0 paradigms with the widespread use of information and communication technologies, including virtual reality and digital twins. To implement digital non-destructive testing, service-oriented approach is proposed as an effective solution for obtaining, processing and storing data of the results of various types of testing, the basic architecture of this solution is given. The simulator’s model of the industrial radiography laboratory is considered, discrete models of objects’ digital twins are constructed while obtaining an image, for which the basic provisions and tools of set theory are used. Examples are given illustrating the correspondence of mathematical models of digital twins to their graphical counterparts, as well as the image formed on the detector as a result of modeling and performing a radiation type of non-destructive testing. It is noted that the virtualization of such a complex technical facility as an industrial radiography laboratory allows for a short period of time and at minimal cost to verify the feasibility of technical solutions and engineering hypotheses taking into account real production conditions and needs, while providing, on the one hand, variability in the implementation of technological operations, and on the other – the number increase of trained qualified specialists according to the radiation type of non-destructive testing.
